Ornamentation and Structure

LM  ornamentation LM: reticulate,  nexine: -,  sexine: -,  SEM  ornamentation SEM: reticulate, heterobrochate,  suprasculpture SEM: -,  TEM  tectum: semitectate,  infratectum: columellate,  foot layer: continuous,  endexine: absent,  intine: monolayered,  wall peculiarities: -,  supratectal element: -

Miscellaneous

pollen coatings: pollenkitt, primexine matrix,  reserves in cytoplasm: -,  cell number: 3-celled,  Ubisch bodies: absent

Annotations: The footlayer is very mighty, forming lamellae in apertural regions.
